Abstract:
Lighting devices are disclosed having a light-transmissive resin sheet and one or more light sources disposed within the light-emitting resin sheet. The light sources may, in some embodiments, be oriented so that a large portion of light emitted from the light sources exhibits total internal reflection within the light-transmissive resin sheet and is trapped inside the sheet. This total internal reflection may, for example, advantageously provide a more uniform light emitted from the lighting device when scattered from objects inside the sheet. Methods of making and using the lighting device are also disclosed.
